Music meets robotics: a prospective randomized study on motivation during robot aided therapy

Area of Science:

• Robotics
• Neurorehabilitation
• Human-Computer Interaction
• Music Therapy

Background:

• Robotic-assisted therapy is established for neurorehabilitation motor training.
• Music enhances motor function and motivation in rehabilitation.
• This study integrates music creation into robotic arm therapy.

Purpose of the Study:

• To assess the effects of creativity promotion and visual display on motivation during robotic-assisted arm therapy.
• To investigate user preference between creative and non-creative conditions.
• To evaluate the feasibility of a music creation task in a robotic therapy setting.

Main Methods:

• A prospective randomized study with 16 healthy participants.
• Four training conditions were tested: creative (C+) vs. non-creative (C-), with (V+) vs. without (V-) visual display.
• Motivation was measured using the Intrinsic Motivation Inventory (IMI), alongside training time, velocity, perceived effort, and perceived training time.

Main Results:

• Promoting creativity (C+) significantly increased interest/enjoyment (p=0.001) and perceived choice (p=0.010).
• Creative conditions were preferred over non-creative ones.
• An interaction between creativity promotion and visual display omission affected training time and intensity.

Conclusions:

• Integrating creativity into robot-assisted therapy enhances motivation.
• The developed visuo-audio-haptic and audio-haptic music creation system is feasible.
• The system is recommended for patients with neuromuscular disorders.
